X-ray evaluation of supraacetabular sclerotic zone in the long-term results of total hip replacement.
The present study has been undertaken to analyse variability in the supra-acetabular sclerotic zone during a follow-up of 2-10 years after a total hip replacement. The material comprises 124 cases of Mc Kee Farrar and Weller total hip prosthesis. The criteria of clinical and radiological evaluation were based on literature data. The size of the supra-acetabular sclerotic zone was assessed planimetrically. A relationship between the size of the supra-acetabular sclerotic zone, the acetabular cup inclination and its fixation was found. In cases of excellent and good clinical results the size of the supra-acetabular zone had been decreasing. In cases of poor and fair results, in our study, the size of the supra-acetabular sclerotic zone increased.
